It is is adapted to be visually displayed. The operation panel 23 is provided with an auditory notification switch 27 and an auditory notification unit 28, so that the magnitude of the heating output of the heating source is notified as needed.
[0010]
As shown in an enlarged view in FIG. 2, the visual display unit 26 is composed of LEDs and the like. When the heating output of the heating source is small, the small yellow form 26a, when it is medium, the orange form 26b is large. It is visually displayed as a flame form by the red form 26c. In addition, the auditory notification unit 28 is constituted by a speaker or the like, and is configured to perform auditory notification based on the loudness of the sound, high, medium, low, and long, medium, and short.
[0011]
FIG. 3 is a block diagram showing the configuration of the visual and auditory control circuit 30 used in the heating cooker 20. The visual auditory control circuit 30 is provided with the input switch 24. The heating switch 25 is connected to the input switch 24, and the current of the heating source 31 such as an electromagnetic induction winding is adjusted to control the heating output.

A controller 32 having a CPU or the like is connected to the heating controller 25, and a heating output signal corresponding to the heating output adjusted by the heating controller 25 is output to the visual display unit 26, and the sound synthesizer 33 and auditory notification are also output. The sound is output to the auditory alarm unit 28 via the switch 27.
[0013]
When the sound synthesizer 33 receives the heating output signal, the sound synthesizing unit 33 converts the heating output signal into a sound synthesizing signal corresponding to the heating output signal, such as a loudness, high / low / long / short sound. The sound synthesis signal synthesized by the sound synthesizing unit 33 is sent to the auditory alerting unit 28 via the auditory alerting switch 27 to generate a loud sound corresponding to the heating output and auditoryly notify it.
[0014]
Note that the auditory alert switch 27 is always on, and the auditory alerter 28 operates together with the visual display 26. However, when the auditory notification unit 28 is not necessary, for example, when the visual display unit 26 can be sufficiently displayed, or when the sound of the auditory notification is noisy, it is turned off and the auditory notification unit 28 is not activated. Can be. When a heating output signal is input, the visual display unit 26 displays the state of the heating output as a change in the color, brightness, etc. of the LED.
[0015]
FIG. 4 shows an example of the heating output signal of the heating source output from the controller 32 to the visual display unit 26 and the sound synthesizer 33. When the heating output of the heating cooker 20 is adjusted to 1,000 W (hereinafter referred to as “P1”), a continuous large current signal A1 is generated from the controller 32 as shown in the upper part of FIG. When the output is adjusted to 800 W (hereinafter referred to as “P2”), an intermittent medium current signal A2 is generated and the heating output is set to 600 W (hereinafter referred to as “P3”) as shown in the middle stage of FIG. When adjusted, an intermittent small current signal A3 is generated as shown in the lower part of FIG.
[0016]
When this heating output signal is output to the visual display unit 26, the display of the visual display unit 26 is performed by a large red form display 26c when the current signal A1 is large, and a medium orange color when the medium current signal A2 is displayed. In the case of the small current signal A3, the yellow form display 26a is used. Since such a visual display displays the magnitude of the heating output in various forms, the user can easily grasp it.
[0017]
When the large current signal A1, the medium current signal A2, and the small current signal A3 are output to the sound synthesizer 33, sound synthesis is performed. This sound synthesis signal is output to the auditory notification unit 28 via the visual notification switch 27. In the case of the large current signal A1, a loud sound as shown in FIG. 5 is generated, and in the case of the medium current signal A2, the medium sound is generated. And a small sound is generated in the case of the small current signal A3.
